VALVE-GUARD FOR NON-REFILLABLE BOTTLES.

SPECIFICATION forming part of Letters Patent No. 795,029, dated July 18, 1905.

Application filed November 15I 1904. Serial No. 232,829.

To all 1117710711 it may concern:

Be it known that I, EDMUND I. DOLE, aciti- Zen of the United States, residing at \Vashington city, in the District of Columbia, have invented certain new and useful Improvements in Valve-Guards for N on-Refillable Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in guards for the valve mechanism of non-refillable bottles, and while desirable for use in connection with any and all kinds of valve mechanisms it is particularly adapted for use with such as is shown and described in a pending application for Letters Patent for non-refillable bottles executed by me of even date herewith and bearing Serial No. 232,830.

My invention has for its object to provide a guard which shall not only be simple and economic of construction, but which shall be highly effective for the purpose designed.

WVith these ends in view my invention consists in the novel details of construction and arrangement hereinafter more fully explained.

In order that those skilled in the art to which my invention appertains may know how to make and apply my improved guard and to fully understand its advantages, I will proceed to describe the same, referring by numerals to the accompanying drawings, in which Figure 1 represents a central vertical section of the neck portion of a bottle with valve mechanism located therein and protected by my improved guard. Fig. 2 is a transverse section on the line a 7) of Fig. 1. Fig. 3 is a similar section on the line 0 (Z of Fig. 1. Fig. 4 is a central vertical section of the guard, taken at a right angle to that shown at Fig 1 and showing a modification of construction; and Fig. 5 is a similar view showing another modified form of construction.

Similar reference-numerals indicate like parts in the several figures of the drawings.

1 represents the neck of a bottle, and 2 a valve mechanism for controlling the outflow of the fluid contents and preventing the refilling of the bottle. The valve mechanism shown is such as is described and shown in the pending application hereinbefore referred to and need not be here more particularly described.

My improved guard for protecting the valve mechanism against any fraudulent attempt to manipulate the same in order to accomplish the refilling of the bottle consists, preferably, of a tube of different diameters, connected by a horizontal shoulder, the lower portion 3 of substantially the same diameter as the interior of the neck of the bottle and the upper portion 4. of reduced diameter and of such area as to permit a ready outflow of the contents of the bottle and to receive an ordinary sealing-cork. The portions 3 and 4c are joined, as shown, by a shoulder '5, and 6 is-a gasket or packing of cork or other suitable material for forming a liquid-tight joint between the upper part 4 and the neck of the bottle. About midway between the shoulder 5 and the lower extremity of the lower portion 3 of the tube is located an inverted sheet metal cup 7, formed with diametric slots for the passage of the ends of a spring 8, which enter a circumferential recess or groove in the neck of the bottle, as clearly shown in Fig. 1, thus securing the inverted cup in position within the enlarged portion 3 of the guard receptacle or tube and also looking the latter in fixed relation with the neck of the bottle. The enlarged portion 3 of the tube is also provided with diametric openings for the passage of the ends of the locking-spring 8.

The inverted cup 7 is formed with guards 9, produced by cutting the metal at the circumference and turning it up, as shown at Figs. 1 and 3, and leaving radial supports 10 and producing liquid-passages '11.

WVithin the lower end of the enlarged portion 3 of the tubular receptacle is located a ring-shaped member 12, having a central liquid passage-way 13, surrounded by an annular trough or cul-de-sac 1 1. The ring-shaped member 12 is preferably held in fixed relation with the lower portion of the tubular receptacle by frictional contact, but may be secured thereto in any other desirable manner.

Instead of forming the tubular guard-receptacle as shown in Fig. 1 it may be made in the form shown at Fig. 4 to produce an annular recess 15, adapted to receive a ringpacking instead of the more extended packing shown at Fig. 1 and to admit of a larger cork within the upper end of the part 4, or, as shown at Fig. 5, the upper portion of reduced diameter may be entirely dispensed with, in which case the tubular receptacle 3 may be made to fit theinterior of the neck of the bottle with sufiicient exactness to justify dispensing with the packing, and when so constructed the sealing-cork will be secured in the upper end of the neck of the bottle in the usual manner. Although I have shown the modified constructions illustrated in Figs. 4: and 5, I prefer the use of that form shown at Fig. 1.

When the parts are constructed as shown and described and locked within the neck of the bottle in such position that the ring-shaped member 12 is immediately above and adjacent to the cap or cover of the valve mechanism 2, the latter will be thoroughly protected against any fraudulent attempt to manipulate the same, for, as Will be readily comprehended, should a flexible wire or any specially-constructed implement be introduced through the center of the tubular guard-receptacle it will first come in contact with the closed portion of the inverted cup 7, and an entrance to 5 the liquid-passages 1 1 will be prevented by the vertical guards 9; but should it be possible to pass said guards and enter the liquidpassages 11 the advance end of such wire or implement would be led into the annular trough or cul-de-sac 14 and prevented from passing down through the central liquid-passage 13 to the valve mechanism, and thus render it impossible to tamper with the same. While full protection is thus afforded the valve mechanism, ample opportunity is provided for a full exit flow of the fluid contents of the bottle.

The several parts of my improved guard may be economically constructed of sheet metal by suitable forming-dies in a droppress, and, as will be seen, they may be expeditiously assembled and readily adjusted and located in position within the neck of the bottle, and when so adjusted and located in fixed position by the spring 8, the latter being inaccessible for manipulation, it will be impossible to remove the guard without destroying the same.

Having described the construction and advantages of my improved valve-guard, what I claim as new, and desire to secure by Letters Patent, is-

1. A valve-guard located within the neck of a bottle above the valve mechanism and in liquid-tight relation with the neck of the bottle and consisting of a tubular member having diametric slots for the passage of a retaining-spring; an inverted-cup-shaped member provided with liquid-passages and a nonperforate portion and with upwardly-extending barriers between the non-perforate portion and the liquid-passages of said member; a locking-spring having its extremities passing through the diametric slots of the tubular member and seated within a retaining-recess in the neck of the bottle, and a ring-shaped member formed with a central liquid-passage surrounded by a walled trough, and located within the base of the tubular member, substantially as and for the purpose set forth.

2. In combination with the neck ofa nonrefillable bottle formed with a recess for the reception of the ends of a locking-spring, a valve-guard located above the valve mechanism and consisting of a tubular member of different diameters at opposite ends of an intermediate shoulder; an inverted-cup-shaped member located below the intermediate shoulder; a ring-shaped member having a central liquid passage-way surrounded by an annular trough and located within the base of the tubular member; a diametric locking-spring passing through the diametric slots in the tubular member and with its ends located within the recess formed in the neck of the bottle, and a packing or gasket interposed between the upper portion of the tubular memher and the neck of the bottle, substantially as shown and described.

3. In combination with a non-refillable bottle, a guard for the valve mechanism thereof, consisting of a tubular member of ditferent diameters with an intermediate shoulder located in liquid-tight relation with the interior surface of the neck of a bottle; an invertedcup-shaped member located within the tubu' lar member and having a closed central portion surrounded by vertical liquid passageways, and vertical obstructions between said passage-ways and the closed central portion; a ring-shaped trough located within the tubular member and below theinverted-cup-shaped member; and means for locking the assembled members within the neck of the bottle, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

EDMUND P. DOLE.
